Influenza may cause some people to become very ill. Dehydration and pneumonia are major complications of influenza. Regardless of the altruism of not exposing other people to infection, sick people should seek medical care if it is needed. Guidelines have been spelled out clearly by the CDC and how they apply to various groups.

The story of swine flu will be played out in real time over the next several weeks and months. Previous epidemics have taught the world many lessons in how to deal with the potential spread of an influenza virus. History will judge how well we have learned.
